Radiometric dating activity answers Sex chat with married aunt online
The first post question caused some confusion: Why didn't each group get the same results?
A lot of the students said because they shook the containers differently... I also have students wash their hands before the activity, because of course after, the students eat the M&Ms. Radioactive decay and half-lives can be a very difficult concept for our 8th graders to grasp.
They not only enjoyed this activity, but they really gained a better understanding of it as well.
PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.
They will only re shake the radioactive M&Ms each time. Once they are finished with their 8 runs, they will record their data on the class data table (which can be on the board).
Once all groups data is on the table, you can calculate the average for each run (1-8) and determine a class average.
Time factors of millions and billions of years is difficult even for adults to comprehend.
Equipment that is necessary is M&Ms-- a lot because each group needs to begin with 100, and a container with a cover for each group.
Students should have the skill to set up a data table and a graph, however, if you want to use this activity with students that have not, you can provide them a template with that information.
Students use M&Ms to demonstrate the idea of radioactive decay. Parent isotopes are represented by the M side up (radioactive).
Paul, MN, based on an original activity retrieved from also with the help of Jenni Johansen (other 8th grade science teacher at So. Paul Junior High School In this activity, students gain a better understanding of radioactive dating and half-lives.
